Phase locking fails above 5 kHz, so high-pitch perception relies on place theory

Evidence

The low-frequency stimulus was a spectrally shaped multicomponent complex (SSMC), which was a harmonic complex with a fundamental frequency (F 0 ) of 100 Hz. The spectral envelope had a flat passband and sloping edges (5×F 0 centered at 1100 Hz).The overall level of the complex was 54 dB SPL. Threshold equalizing noise, extending from 125 to 15,000 Hz, was added. The high-frequency stimulus was a ˵transposed stimulus,˶ which was a 4-kHz tone carrier amplitude-modulated with a half-wave rectified 125-Hz sinusoid (Bernstein and Trahiotis 2002 ). It is considered that the auditory-nerve firing is phase locked to the modulator waveform, which provides the cue for judging the ITD and modulation rate of the stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1031 (#complicates, via linked claim)
